The flipped classroom does not address all the limitations of the brick-and-mortar school. Although in the best flipped-classroom implementations, each student can move at her own pace and view lessons at home that meet her individual needs rather than those of the entire class, most flipped classrooms do not operate this way. As Selman Khan, the media’s personification of the flipped-classroom, observes in The One World Schoolhouse, “Although it makes class time more interactive and lectures more independent, the ‘flipped classroom’ still has students moving together in age-based cohorts at roughly the same pace, with snapshot exams that are used more to label students than address their weaknesses” (see “To YouTube and Beyond,” book reviews, Summer 2013). This arrangement also doesn’t tackle the root causes of the lack of motivation that persists among many low-achieving students.
